摘要：
A single compression engine transmits first and second discrete cosine transform (DCT)-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of a plurality of DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the plurality of DCT coefficients.
